My uncle is/was Australian. He once spent eight weeks with us - I watched him put vegemite on everything we put in front of him. I cannot imagine what happened in Australia that made them think that stuff is edible, but good god, they love it. It's far, far worse than poi. But worse than both - and please don't even try to debate this because I'll ban you forever - is Hákarl, Google it. It's so, so rough.
